CDC: Flu Vaccine 48% Effective This Season, But It's Working Pretty Well

The U.S. Centers from Disease Control and Prevention recommends that everyone older than 6 months should get an influenza vaccine.

'It's good news and underscores the importance and the benefit of both annual and ongoing vaccination efforts this season'. 11 more deaths are in the process of verification as influenza-caused.

The flu shot is an inactivated influenza virus.

48 percent effectiveness might not seem like a lot.

The Idaho Bureau of Laboratories reports four different influenza viruses are circulating in Idaho this season.

The number of people hospitalized as a result of the flu varies from year to year. The committee members consider which viruses are making people sick, where those viruses are spreading and how well the previous season's vaccine protects against them.

Anyone who has not yet received his or her flu shot should do so as soon as possible, as it takes two weeks for the body to build the resistance given by the vaccine, officials say.

This flu season, which is considered to have started October 1, is one of the most severe flu seasons in the state since 2000, said Chris Smith, spokesman for the Idaho Department of Health and Welfare.

During the 2015-2016 season, vaccine effectiveness was 47% - about the same as this season. While seasonal flu-related deaths of people older than 18 years of age are not reportable, those among children are reported.

Flannery explained that there are differences depending on age or even the immune status of the person being vaccinated. "So there are individual factors as well as the circulating viruses that influence vaccine effectiveness".

'You won't have to be admitted to the hospital, you won't have to go to the ICU, and you won't die'. Plus, we should be getting the shots not just to protect ourselves but to protect coworkers and family members who are more vulnerable to serious complications.

'So half a loaf is better than none. "If you haven't yet gotten the vaccine, it is not too late!"

"But for H3N2, it's as good as we have seen for some of the H3N2 seasons that have been well matched".

Because flu cases are expected to occur through March, Dr Schaffner says there are plenty that can be prevented or made less severe. "It's better to be protected and have 50 percent less chance of getting sick from the flu than to be completely vulnerable to the flu", Rigler said.
